Programmable Parameters
Some features have individual parameters that are customizable; the details of these
programmable parameters are given in a reference table. The reference table is

PEC 013 Page 5of 71 12/20/13
divided into three columns: “Parameter Name”, “Number”, and
“Min/Max/Default/Unit”. The “Number”column references a code number to identify
the parameter during the ordering or the aftermarket parameter setting change
processes. The “Min/Max/Default/Unit”column defines the minimum and maximum
values of the parameter setting. If the parameter is not altered during specification of
the vehicle, the default setting is delivered from the factory. The units associated
with a parameter are labeled after the value of the parameter.

Nonprogrammable Parameters
Unchangeable parameters, also known as nonprogrammable parameters, are used
to assist in the explanation of a feature. A reference table is provided which is
divided into two columns: “Parameter Name”, “Default/Unit”. The “Parameter Name”
column identifies the parameter. The “Default/Unit”column defines the default or
standard value and unit associated with it.

ON/OFF Requirements
To define when a feature is enabled/ON or disabled/OFF, a reference table is used
to detail the required conditions. The table is divided into two columns: ON and OFF.
In each column there is a list of conditions that must be met for the feature to be ON
or OFF. Also, both columns include a stipulation of “All”or “Any”in parentheses.
“All”indicates that every condition listed in the column is required to turn the feature
ON or OFF. “Any”indicates that only one of the conditions listed in the column is
required to turn the feature ON or OFF.

Activate/Deactivate Requirements
After a feature is ON, the function may not activate until it is triggered. A trigger is a
certain event or action by an operator. Conversely, the function may not be
deactivated until another event or operator action is taken. A function or feature may
still be ON even when it is deactivated. To define the trigger points for activation and
deactivation a reference table is given, listing the conditions required. The table is
divided into two columns: “Activate”and “Deactivate”. In each column there is a list

PEC 013 Page 6of 71 12/20/13
of conditions that must be met for the feature to be activated or deactivated. Also,
both columns include a stipulation of “All”or “Any”in parentheses. The “All”
indicates that every condition listed in the column is required to activate or deactivate
the feature. The “Any”indicates that only one of the conditions listed in the column is
required to activate or deactivate the feature.

4.0 Engine Ratings
Overview
The engine rating states the peak power and torque of the engine. The engine is
available with several power ratings, allowing the engine to provide the correct
amount of power to complete the job while limiting the torque within driveline
component limitations. All power ratings are programmable without changing
hardware on the engine; however, increasing the power rating may put main
driveline components at risk for premature wear or damage. Three of the ratings are
available with multi-torque; these ratings are identified by the MT in the option name.

5.0 General Settings
Overview
Basic engine parameters.
Standard Feature
Maximum Vehicle Speed
High Exhaust System Temperature (HEST) Warning
Fuel Density
“Maximum Vehicle Speed (N162)” defines the maximum operating governed speed
of the vehicle when cruise control and Vehicle Speed Limiter is not active.
High Exhaust System Temperature (HEST) Warning allows the engine to inform the
operator when the exhaust temperature exceeds “HEST Warning Temperature
Activiation Limit”and the vehicle speed is less than HEST “Warning Minimum
Vehicle Speed (065)”.
“Fuel Density (N051)”allows the customer to reprogram the engine controller with a
fuel density that more accurately represents the local variation in fuel density used in
their vehicles. This will, in turn, increase the accuracy of the controller’s calculated
fuel economy.

6.2. Engine Idle Shutdown Timer (EIST)
Overview
The Engine Idle Shutdown Timer (EIST) is a valuable tool for fleets to restrict idle
time and improve fuel economy. The EIST can be limited to a predetermined interval
and may be overruled during extreme weather conditions. The EIST is
programmable to respond to engine coolant temperatures which allows for longer
uninterrupted warm-up time intervals. The EIST can be programmed to have more
than one time interval based on whether the parking brake is set or not set. The
engine load can be used to reset the EIST. While in power take-off (PTO) mode, the
EIST can be turned ON or OFF with a specific time interval while in PTO Mode. The
EIST is configured at the initial sale of the vehicle and some programmable
parameters are locked or tamper resistance until the expiration mileage is reached.
Standard Feature
EIST
EIST initiates when engine speed is at idle, vehicle speed is at 0 mph, and the
accelerator pedal is motionless or not depressed. The interval of time until the
engine shuts down is programmable; there are two programmable settings for this.
One is with the parking brake ON and the other is with parking brake OFF. A
warning message in the truck’s driver display will indicate that shutdown is
imminent, with the customer able to program when the warning should first notify the
customer and countdown to shutdown of the engine. Within the standard feature
there are a number of programmable features:
Coolant, Oil, and Fuel Temperature Overrule
Programmable resets

PEC 013 Page 14 of 71 12/20/13
Temperature Overrules allow the engine to idle while coolant, oil and fuel
temperatures are below calibrated settings.
Programmable Resets are signals from equipment on the vehicle that the operator
actuates. The reset can be turned ON or OFF. If the reset is ON when the
equipment is actuated, the EIST counter will restart. Programmable resets may only
occur once the operator has received notification of an impending shutdown on the
driver display. For example, when the EIST is set to 5 minutes with the accelerator
pedal reset ON and the vehicle was idling for 4 minutes, a message of an impending
shutdown will appear on the driver display and an actuation of the accelerator pedal
will reset the timer and delay the engine’s shutdown for another 5 minutes (total idle
time is 9 minutes). Below is a list of resets that may be programmed by the
customer:
oAccelerator Pedal
oClutch Pedal
oParking Brake
oService Brake
oEngine Load
Feature Options
Ambient Air Temperature Overrule
EIST with PTO Mode
EIST Engine Load Overrule
Ambient Air Temperature Overrule allows the engine to maintain operation without
shutdown when the temperature is above “High Ambient Air Temperature Overrule
(N184)” or below “Low Ambient Air Temperature Overrule(N185).”
EIST with PTO Mode allows the EIST to shutdown the engine when PTO Mode is
active. The same conditions must be met for the EIST to shutdown the engine,
except programmable resets. An EIST shutdown may occur at any point in EIST
with PTO Mode.
EIST Engine Load Overrule allows the engine to maintain operation without
shutdown when the engine load is above “Engine Load Threshold (N183).” Engine
Load Overrule is only available when “Reset EIST Timer Based On Engine Load
(N190)” is turned OFF. This feature is not available with EIST in PTO Mode.
